MariaDB high memory usage during scheduled backups

Mariadb usually consumes 10-11% (as reported by Process Manager) on regular days but when my scheduled incremental backup runs, it shoots to 30% and doesn't return back to normal without being restarted.

I just recently upgraded from MySQL 5.6 to MariaDB a few weeks ago. I'm using tokudb by default storage engine (as recommended) while old tables are still with MyISAM and InnoDB. InnoDB cache is set to 5GB.

You may also want to run a tuner after letting MariaDB run for at least 24 hours. This may prompt more user-feedback. Otherwise, you may want to consult with a system administrator for assistance with optimizing your MariaDB performance:
